I am not sure either of the name, but I have them wandering around in my garden. A friend gifted them to me many years ago, she called them Clustered bell flowers. Not a technical name. They are a pretty purple though!

Hi Everyone, I'd wondered about "Campanula," myself, as there are so many varieties, but Sylvana gave us the positive ID. Capanula glomerata (also called Clustered Bellflower)! Yea!! Thanks so much!! They are described as fairly aggressive, but not terribly so. The advice I found was to separate them from time-to-time. So, in about 2 or 3 years, I'll be sending a few out of the garden. Get in line! ;-)

And they seem so well behaved at the bank! Oh well, I already have a problem bellflower in my garden - I don't need two of them. Unless I could set up a campanula cage match! Yeah, that would be worth it.

I was going to say that Sylvana is right, but see you already figured it out. I was given some by a neighbor when we first moved in. I pulled most of it out when I saw how spready it was. Be careful, because not all of it stays pulled, and it takes persistence to keep it out of where you don't want it.

I have a little clump in the small bed under our tree that I decided to let grow after if kept coming back. It can't go too far, but still, I have to pull some each year to protect the other plants in the bed. It does have some gorgeous blooms this year, and I forgot to include them in my GBBD post.

I was trying to remember if they reseed or not, but I deadhead the few I have, and don't give them a chance to.

That's what I do with garlic chives, which I know do. They have such a pretty white bloom, though, so I let them go until it looks like the seeds are forming, then I cut them back like I do the regular chives, clear to the dirt, and throw the seed heads in the garbage.

I just planted this this year - one plant - but it's in a small raised bed, so it probably can't do too much harm there. A friend has this (I discovered AFTER I bought one) and it grows quite aggressively. She's always ripping it out.

Many campanulas are aggressive, but I really love them all, so I'll manage them. :-)

Kylee, I do have a great article on the variety of campanula. It describes the various types and how aggressive or non-aggressive they are. However, I'm with you. I like them and I'll work with it. ;-)
